SOA Overview<\/h2><\/span>\n

* SOA is BAD (Business Agility through Decoupling)<\/p>\n

SOA Architectural Principles<\/h3><\/span>\n

* Interop across platforms via open standards (ws-*)
\n* Loose coupling via contracts (e.g. WSDLs)
\n* Service encapsulation
\n* Service autonomy
\n* Service reusability
\n* Service discoverability<\/p>\n

Service Characteristics<\/h3><\/span>\n

* Granularity
\n* Atomicity
\n* Idempotency
\n* Statelessness
\n* Composibility
\n* Event awareness<\/p>\n

Service Layerings<\/h3><\/span>\n

* GUI layer
\n* Business process layer
\n* Service and event layer
\n* Service implementation layer<\/p>\n

ESB<\/h3><\/span>\n

* Sits between service consumers and service providers (decoupling)
\n* May provide (OSB)
\n– Endpoint virutalization
\n– Routing
\n– Transformation
\n– Validation
\n– Auditing
\n– Messaging
\n– Synch\/Asynch adaptation
\n– Composition<\/p>\n

Governance<\/h3><\/span>\n

* Publish service
\n* Service life cycle management<\/p>\n

Events and EDA<\/h3><\/span>\n

* EDA: Event Driven Architecture
\n* Implementations
\n– JMS
\n– BPEL sensors
\n– ESB routing rules<\/p>\n

BAM<\/h3><\/span>\n

BAM: Business Activity Monitoring<\/p>\n

CEP<\/h3><\/span>\n

CEP: Complex Event Processing
\n* Aggregate simple events to derive meaningful patterns (BI)<\/p>\n

SCA<\/h2><\/span>\n

* First published in 2007
\n* Help simplify assembly and deployment of compostie applications.<\/p>\n

Web Cernter<\/h2><\/span>\n

* Oracle homegrown portal product
\n* Based on ADF
\n* Supports WSRP (both publishing and consuming protlets)
\n* Provide UI level integration for
\n– content management
\n– task management\/workflow
\n– search
\n– communication(email, chat, VoIP, etc)<\/p>\n

vs ADF Workflow<\/h3><\/span>\n

* ADF workflow
\n– uses Oracle proprietary format so not suited for enterprise integrations
\n– integrated at design time (from ADF libs)
\n* WebCenter Portlets
\n– based on industry standards so good for cross enterprise integrations
\n– integration happens at run time (slight performance hit but easy to change)<\/p>\n

ADF<\/h2><\/span>\n

* ADF is a Oracle homegrown MVC application framework for developing enterprise Java\/J2EE applications
\n* JSR-227 (in process)
\n* Supports multiple UIs
\n– web app
\n– desktop app
\n– web services
\n* ADF apps run on J2EE app server, mainly WebLogic
\n* Uses JDev as IDE
\n* Components
\n– ADF BC
\n– ADF Faces
\n– ADF Model
\n– ADF Controller (extenstion to JSF controller)
\n* FMW applications are built on ADF including:
\n– WebCenter
\n– Oracle Apps
\n– BI EE
\n– BAM Studio
\n– EM
\n– SOA human tasks
\n* Also support
\n– task flows
\n* ADF applications can be bundled into library (jar) files and reused<\/p>\n

Special Features Used in SOA Suite<\/h3><\/span>\n

* Rase events onto the EDN (Event Delivery Network) from ADF BC
\n* UI for human tasks in BPM Worklist application
\n* UI for BAM data control
\n* Integration of BPEL entity variables with ADF BC via SDO binding<\/p>\n

ADF Architecture<\/h3><\/span>\n

* Two parts implemented in separate JDev projects in a single application
\n– Model
\n– ViewController
\n* Decouples UI from business components <\/p>\n

Model<\/h4><\/span>\n

* Contains business objects<\/p>\n

ViewController<\/h4><\/span>\n

* Renders UI
\n* Injects data to UI from model via data bindings<\/p>\n

\n– Supports variables
\n– Better VETRO support (VETRO: validate, enrichment, transform, route, operate)
\n– Can implement composite services (mediator can not)

* Services exposed by OSB are called Proxies
\n* Can receive messages from
\n– HTTP(S)

\n– File
\n– Java on the Bus

\n– SOA Suite
\n* OSB has its own security framework based on WS-Policy
\n– Based on WS-SecurityPolicy (WSSP) 1.2
\n– Can be used to virtualize services and implement security policies (OWSM is preferred though)
\n* Supports throttling (queue up requests)
\n* Supports split-join (join up requests)<\/p>\n
